half way to the base. The ovipositor is characterized by the regularity 

 of the teeth of the lateral pieces each of which bears about ten teeth or 

 ridges. 



Distribution: The only record of this species for the state 

 is that given by Mr. Wm. T. Davis who reports a single speci- 

 men from Kansas in the Museum of Comparative Zoology. Van 

 Duzee gives North Carolina, Georgia, Florida, and Alabama 

 as the other states in which it occurs. Davis reports specimens 

 from Mississippi and Louisiana in addition. Thus it is seen to 

 be a distinctively southern species. 



Remarks: Davis reports this species as being found in the 

 sand ridges in North Carolina. The specimens examined were 

 kindly sent me by him from this state.

A greenish-brown and black or nearly fulvous and black species of 

 very large size. This is the largest of our cicadas, the specimens at hand 

 measuring from 40.5 to 42 mm. 



Color: Head black, marked with greenish-brown as follows: A spot 

 along antennal ledges which broadens on towards the eyes, an elongate 

 median spot on upper portion of front, a median and two lateral spots at 

 base of front, and irregular spots beginning laterad of the lateral ocelli 

 and extending along posterior margin to the eyes. Pronotum mostly 

 greenish-brown, with two, black, triangular, median spots tapering pos- 

 teriorly to the collar and enclosing an elongate light stripe and each, in 

 our specimens, with a fulvous spot in anterior portion. The portion back 

 of the eyes is also black and connects with a black narrow line which 

 runs along the groove in front of the collar. The lateral margins are 

 narrowly black. Mesonotum mostly black, the median arms of the W 

 being fulvous, these fulvous lines broadening and extending laterad and 

 caudad to the cruciform elevation which is greenish-brown. The lateral 

 margins of the mesonotum are also fulvous. Abdominal terga black, the 

 basal segment and the last three segments being pruinose in fresh speci-
